Enable desktop on the raspberry pi

I was trying out booting my pi4 into a chromium kiosk mode for a demo and ran the commands from the following post:
Open chromium full screen on start up

@xset s off
@xset -dpms
@xset s noblank
@chromium-browser --kiosk http://google.com/ 

Now when I went to that file again it seems to be empty and I’m not able to revert the change.

I tried looking for the reverse commands like

@xset s on
@xset s blank

Here’s the output of I got from the commands in the comments:

pi@raspberrypi:~ $ ls -l /home/pi/.config/lxsession/LXDE-pi/autostart
-rw-r--r-- 1 root root 37 Jul 24 16:05 /home/pi/.config/lxsession/LXDE-pi/autostart
pi@raspberrypi:~ $ cat /home/pi/.config/lxsession/LXDE-pi/autostart
@xset s on
@xset -dpms
@xset s blank
